RAIL-TIE.

Specification of Letters Patent.

Patented J an. 28, 19-13.

Application filed October 8, 1912. Serial No. 724,570.

To all whom it may concern Be it known that I, ABRAHAM EBERHART, a citizen of the United States, residing at- Miffiinburg, in the county of Union and State of Pennsylvania, have invented new and useful Improvements in Rail-Ties, of which the following is a specification.

This invention relates to railties and the object of the invention is to provide a simply constructed and durable tie at a cost not greatly exceeding the cost of the ordinary wooden tie.

A further object of the invention is to provide a tie of this character so reinforced that it will withstand all compressions and tensile strain and which will be effective to support rails properly irrespective of the number of cracks or breaks in the body of the tie.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying "drawing which forms a part of this application, and in which Figure 1 is a top plan View of the tie with parts broken away to show one layer of the reinforcing material therein. Fig. 2 is a side elevation. Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2. Fig. t is a vertical transverse section on the line 44 of Fig. 2. Fig. 5 is a similar Section on the line 5-5 of Fig. 2. Fig. 6 is a perspective view of one of the locking blocks. Fig. 7 is a similar view of a locking block used where fish or joint plates are used. Fi 8 is a perspective view of the plate lockmg key used. Fig. 9 is a similar view of the spike. Fig. 10 is a perspective view of an adjustable locking block.

Referring more particularly to the drawings 1 represents the body of the tie which is preferably constructed of cement comsounded in any approved manner; Embeded in the tie adjacent the bottom thereof is a strip of wire fabric 2 the strands of which are of sufficient strength to properly reinforce the tie and to prevent separation of its ends should the cement body crack through the center. This reinforcement is duplicated adjacent the upper side as shown at 3 and intermediate the fabric stri s 2 and 3 there are embedded in the tie suita 1e reinforcing rods 4 which extend outwardly, beyond the tie in handle loops 5. Between these rods and the upper and lower fabric there is embedded in the body of the tie suitable plates 6 which have threaded apertures to receive the rail locking spikes and the plate locking keys to be hereinafter described.

In the construction of the device lockin keys 7 and rail retaining spikes 8 are passed throu h rail supporting plates and positione in a suitable mold with their threaded ends 9 arranged uppermost. A predetermined quantity of cement is thenlaid in the mold around the plates, keys and spikes and mounted upon this cement is the reinforcing fabric 3 through which the keys and spikes pass. Cement is then placed in the mold until the same is approximately one-half filled when the rods 5 are mounted therein and the spike and key plates 6 threaded onto the ends of the spikes and keys before described. More cement is then laid over these rods and nuts and another sheet of fabric 2 is embedded in a final layer of cement as shown. When the tie is partially hardened the spikes and keys are removed and when fully hardened the ties are ready for shipment. In applying the rails the same are seated upon the supporting plates in the position shown in Fig. 2 and the spikes screwed down tightly with their heads overlapping the base of the rail as is usual. Suitable locking blocks 10 are then placed in position on the tie and the keys 7 threaded in position to hold the blocks 10 against displacement. These blocks are preferably constructed as shown with their side edges tapering or thinned out and provided with notches 11 to receive the spikes and with similar notches on the opposite side to receive the keys 7. The blocks may be made slightly wedge shape as shown in Fig. 10 so that they are. adaptable for either a seventy or eighty-five pound rail. The handles 5 projecting from the ends of the body form a convenient means for handling the ties and at the same time the rods upon which these handles are formed provides a durable reinforcing structure. The blocks 10 and their assoclated locking keys 7 are provided to form a reinforced abutment for the spikes to prevent the same from being sheared off by the lateral movement of heavy trains.

What is claimed is 1. A cement tie com rising a body, reinforcing fabrics embed ed therein, and remforcin rods arranged in the body between thegfe rice and the tie.

2. in e cement tie comprlsing a body,

projecting from the ends of separated reinforcing fabrics embedded therein, reinforcin rods embedded in the body between the ebrics, and loops formed.

reeneee threaded into the members, locking blocks carried by the ties, and means threaded into the members for holding the locking blocks in engagement with the spikes.

5. in combination, areinforced cement tie, tapped members embedded therein between the reinforcement, rail hoiding'spikes threaded into the plates, adjustable locking blocks carried by the ties, and means threaded into the members for holding the locking blocks in engagement with the spikes.

In testimon whereof I efix my signature in presence 0 two witnesses.
